The blue and brown wires are the 110V AC voltage input wires so if presumably if you had the mini fridge's AC power cord plugged into a wall outlet and then measured between the blue and brown wires you should measure 110V AC,¹ assuming that your location has 110V -120V AC mains power.
There's also a 12V DC input socket on the mini fridge so if you had the 12V DC power adapter plugged into the mini refrigerator and operated the switch to DC (away from AC) then there should be power on the board.

Are you testing the refrigerator using 110V AC or 12V DC connected to it?

If 110V AC try the 12V DC option and check if that works. If it does it may be a problem with the 110V AC power circuit in the refrigerator. Most probably it converts 110V AC down to 12V DC

There's a 12V DC input socket as well so depending on whether you had the 12V DC adapter cable plugged into the mini refrigerator and operated the switch to DC (away from AC) then there should be power on the board.

Hi @jacklumber
How did you measure the voltage on the blue wire?
